ATTACHMENT FOR TALKI ENG- MAGHINES. I

Application filed April 19, 1915. Serial No. 22,320.

To all whom it may concern:

' Be it known that I, ANDRE J UNon, a citizen of the. Republic of Switzerland, residing in the borough of Manhattan, city, county,

and State of New York, have invented a certain new-and useful Attachment for Talk- Y ing-Machines, of which the following is a specification;

My invention relates to that type of talking machine employing a record carried on the face of a disk which is revolved by. a

suitable motor, andhas for its object to pro duce a device whereby a sound-box or reproducer may be employed for the purpose of reproducing sound from a disk having .a

sinuous record groove in Which the reproducing stylus lS moved laterally relatively to the face of the disk, and the same reproducer maybe employed to reproduce sound from a disk having a vertically out record groove in which the stylus is moved in the direction perpendicular to the plane of the disk. I

A further object is to produce a device whereby the position of the sound-box may be reversed to give access to the needle holder without reversing or in any way altering the position of the tone-arm or any part thereof.

A further object is to-produce a device in which the sound vibrations set up by the dia phragm will be caused to travel into and through the tone-arm without encounteringobstruct-ions and without making sharp I turns.

appear in the following specification and I accompanying drawings considered together These and further objects will more fully or separately. I In the; drawings, I Figure 1 is a plan view of my device operating in conjunctionwith a record disk having a sinuous or lateral out groove;

The outer end of the ,tonei, arm is provided with n movable rnember 6,'7 5' a screw 12 .carried by the-socket 11. The

screw 12 retains the end (if the e1bo w' 9 I i'rnits 9oposition, but allows it to turrrto of the slot. The joint'9 is prdvidedwith asimilarsocket which carriesa' s c lewiil'i-which engages a slot 15 in'ol'lfe 6nd ofth j() t 1.0

end. The sleeve also carries a screw 20 which project into the groov 17 and s'efiqte,-hef sleeve in position, at the same timelinnt n the rotatlon of the sleeve to the length? the groove.

A sound-box or speaker 21 is oarriedposition to operate on a, vertic 5 .5 5; providedwith a slot 1 3.'which isengag'ed by the sleeve 18, by means of the followine in striunentalities: The back of the sound box is provided with an annular flange 22, and within this flange is seated the flange 19 of the sleeve 18. On each side of the flange 1%) is an elastic cushion 2i, and the outermost cushion is held in position by a cover 23 through which the sleeve. projects. The soclccts 011 the elbow joint B and 9 and the sleeve 18 are provided with slits to increase their elasticity and permit them. to make close fits: with their cooperating parts without binding.

' The flange 22 is provided with a. slot ,which is engaged by a pin on the flange 19 which will prevent the latter from turning relatively to the former.

The sound-box is provided with the usual diaphragm 27, and with a stylus or. needle 28. I have shown the Stylus 128 as the. ordinary steel needle, but'it will be understood that any approved form of reproducing point inay be employed. l

The operation of my improved device is as follows: \Vhen used in connection with a sinuous record groove the sound-box and connection 7 are .in position, as shown in Figs. 1,2, 5,6 and '7, that is with the connection i-n an approximately horizontal position as viewed from theside and with the -.rearward portions of thc'joints 8 and 9 ex tending in the-same general direction. as the axis of the tone-arm, as viewed from above. The outer extremity of the 01m. 10 will extend at right angles from the horizontal.

plane of the tone-arm, and the plane of the diaphragm will be substantially that of the vertical plane of the tone-arm, and substantially the same as that of the record groove 29 at-thepoint of engagement of the needle and atright angles to the surface of the record. The stylus will engage the groove on the same plane as that of the diaphragm, and the movement of the needle, caused by its engagement with the sinuousities of the groove will be perpendicular to the plane of I the diaphragm;

When it i desired to use a disk having avertical "out or Ed1son groove, the soundbox is rotated 1n the antl clock-Wise dlrectlon the face of the disk.

respectively. This will bring the sound-box into the position shown in Figs. 3. i and 8, that is with the plane of the diaphragm at right angles to the path of travel of the sound-box across the record caused by the spiral couvolutions of the record groove 30, and at an angle of a'pproxiniatcly (30 1 The vertical cut groove. traveling in-the direction of the arrow in Fig. 8, will cause the diaphragm to vibrate, and the sound waves set up by such vibrations will. travel along the unobstructed bore of theconnection 710 the tone-arm and horn.

\Yhen it is desired tov remove or introduce a needle, the sound-box may be rotated until the needle clamp is brought to the top without raising the connection.

In accordance with the provisions of the patent statute, I have described. the principle of my invention together with the apparatus which 1 now consider to -epresehtthe best embodiment thereof, but l desire to have it understood that the apparatus shown is merely illustrative, aiul that the invention can be carried out in other ways withoutdeparting from the spirit of 1113 invention.

Having now described my invention what I claim as new and desire to secure by Let tEl'S Patent of the United States, is as fol lows:

A device of the character described, having. a sound-box, a chamber on the soundboX, a sleeve within the chamber, cushions between the sleeve and chamber, a support engaging the sleeve, a groove in the support,
